WIRE-WRAPPING TOOL.

Application filed December 18, 1919.

T0 all whom t may concern.'

Be it known that I, OswALD FAGHMAN, a citizen of' the United States ofAmerica, and a resident of Lindsey, county of Sandusky, and State ofOhio, have invented certain new and useful Improvements in Tire-TrappingTools, of which the following is a full and clear specification.

The object of this invention is to provide a simple manually-operabledevice for twisting or wrapping the end of a wire around a straightwire, and it is particularly adapted for fastening the end of felicewire around a fence-post in that class of fences where the horizontalstrands are so close together as to prevent the operation of a lever ina complete circle around the main wire, as more fully hereinafter setforth.

Figure l is a side elevation of' the device showing it in operation on afence wire;

liefen-ing to the drawings annexed by reference-characters, a designatesa lever provided with a hub ZJ which is provided with a radial slot cleading to the central recess in the hub. Journaled in this centralrecess is the hub Z of a ratchet-wheel c, said hub being provided with athreaded end on which is screwed a clamp-nut g, this nut being adaptedto bear against one end of the hub b and to draw the face of theratchet-wheel against the opposite end of the hub with a frictionalcontact, said nut g being locked in its adjusted position by means ofone or more set-screws L. The ratchet-wheel and its hub (l are providedwith a radial slot c' which is adapted to register at a certain time inthe operation with the slot c in the hub Journaled in a central passageformed through the hub Z and its ratchet-wheel is a shaft j which islocked against endwise withdrawal by means of a set-screw tappedradially through the hub d, the inner Specification of Letters Patent.

end of this screw entering a circumferential groove Z formed in saidshaft y'. On the end of this shaft j that is adjacent to theratchet-wheel is formed a disk m which bears frictionally against thedisk-like end a of a lever 0 which latter lies alongside the lever. aand is a companion thereto, the exterior surface ot' both levers beingrounded off so that the two levers may be grasped as one andmanipulated. as one in a cert-aiu operation of my tool hereinafterdescribed. The flat disk-like end a is provided with a radial slot j)which is adapted to register at a certain time in the operation withslots c and t', and likewise the flange m is provided with a radial slot(I, the inner end of this slot being extended inwardly to the other endof the shaft j, so as to form a groove fr which extends entirely throughthe device. Aiiixed to the outer face of the flange m is a hook s whichopens radially outwardly and is set at a distance from the centerofrotation of the flange so that it will be bodily rotated a completerevolution when said flange m is rotated. The inner face of the flangem' is provided with an arcuate groove t into which extends anaxially-projecting lug 4u formed on the outer face of the hub o, saidhub o being formed on the outer face of the ratchet-wheel and on whichthe disk-end n of lever 0 is pivoted.

A hooked spring-actuated pull-pawl 'w is vpivotally mounted on a lugformed on the disk n, and a spring-actuated push-pawl jz/ is mounted onthe companion lever a.

In operation, the rotatable parts are adjusted to bring all the slots inradial alinement, as shown in Fig. 6. Then the tool is adjusted so thatthe main wire a will lie in the groove 1", with the hook s adj aoent tothe fence-post. Then the disk-like flange m is rotated by the fingers ofthe operator as far as the llug u and its groove t will permit it to berotated. This rotation of the disk m of course carries with it the shaft.7', but none of the other parts rotate at this time. This rotation ofdisk m carries its slot g out of alinement with the other slots and thuslocks the main strand a from withdrawal out through said other slots.The tool is then ready for the wrapping or twisting operation. The toolis then moved up close to the post and the free end z of the wire islaid in the hook s. Then, by manipulating the levers a and o back andforth in opposite directions (or by holding one lever still andreciprocating the other), the ratcheteivheel -will be given astep-by-step rotory movement independently of the two hubs Z1 and n ofthe levers. This rotary movement of the ratchet-Wheel Will, throughthemedium of the lug u, carry around With it the flange m and thus impartto the hook s a bodily' rotary movement around the main strand e. rlhuscarrying the hook s in a path around the main strand of Wire causes thefree end e of the Wire to be Wrapped tightly around said main strand inconsecutive, closely-spaced coils.

The foregoing operation is particularly desirable Where the horizont-alstrands of the fence are located so close together as to preA vent afree complete rotary movement of the Wrapping tool. My device, however,can be etfectually used in those cases where the Wires are far enoughapart to permit a complete rotation of the tool around the main strand.ln such cases as these, it is simply necessary to grasp both handles aand o and hold them together while the tool is being bodily rotated.lllhen the tool is used in this manner, it Will be understood, ofcourse, that the ratchet devices are not operated and that the tool actsas a simple lever pivoted on the main strand as a center of rotation.

The nature and scope of the invention having been thus indicated and itspreferred embodiment having been specifically described, What is claimedas new is,

l. In a wire-Wrapping tool, a pair of levers each carrying a pawl, aratchet-Wheel arranged between the levers and havin(r hubs on which said.levers are journalec, said levers and ratchet-Wheel and hubs beingradially slotted, a hook-carrying disk journaled in said ratchet-Wheeland provided with a shaft having a Inain-strand-receiving grooveextending its full length, said disk being provided with a radial slot,means being provided to permit the disk to have a limited rotarymovement independent of the ratchet-Wheel hubs.

2. In a tool of the class described, a pair of companion handles spacedsufficiently closely together to` be grasped together by one hand, aratchet-Wheel having hubs on which said handles are journaled, each ofsaid handles carrying a pavvl, one being a pull-pawl and the other beinga push-pawl, a iiange carrying a hook and also a shaft extending throughand journaled in said ratchet-wheel and hubs, said handles,ratchet-Wheel and hubs, and flanges and shaft being slotted for thepurpose set forth, means being provided for causing the iange and itsshaft to rotate with the ratchet-Wheel but permitting it to have anindependent limited rotary motion.

3. In a Wire-Wrapping tool, a pair of levers each carrying a pawl, aratchet-Wheel arranged between the levers and having hubs on which saidlevers are journaled, said levers and ratchet-Wheel and hubs beingradially slotted, a hook-carrying disk journaled in said ratchet-Wheeland provided ivith a shaft having a main-strandreceiving grooveextending its full length, said disk being provided with a radial slot,means being provided to permit the disk to have a limited rotarymovement independent of the ratchet-wheel hubs, said means consisting ofa groove formed in the disk and a co-acting lug formed on one of thehubs of the ratchet-Wheel.

In testimony whereof I hereunto my signature.
